3 Claims; (01. 112-414.

, 1 This: invention. relates -.-to.- a tip for rodswand especiallyttheflexible ribs. of. umbrellas.

The important object of the invention is to provide means. which will receive and hold the tip in correct position for sewing the cloth cover thereto so that the operator cannot make a mistake and put on the tip in a wrong position.

The invention is illustrated on the accompanying drawings and described in the specification that follows and the novel features are defined in the claims:

Figure 1 is a top view of my invention holding the umbrella cover upon the rib;

Figure 2 is a side view of the same parts;

Figure 3 is an enlarged side view of thetip;

Figure 4 is a sectional view of the tip correctly mounted for the operation of sewing the cover thereto;

Figure 5 is an inner end view of the tip;

Figure 6 is a sectional view showing the tip incorrectly mounted so that the needle will be broken if sewing is attempted;

Figure 7 is atop view of the means for supporting the tip for sewing to the cover; and

Figure 8 shows a detail.

The numeral I indicates the body of the tip, which is preferably of metal such as aluminum or of plastic material with a small knob 2 at its outer end and a small longitudinal cavity 3 at its inner end to receive the end of an umbrella rib 4. Near the knob 2 the tip tapers somewhat and is substantially square as at 5, this part having the greatest thickness near the middle. At or near this point is a transverse hole or bore 6. This bore receives the thread by which the tip is secured to the cover of the umbrella.

The tip is sewn to the cloth by slipping it on a rod or mandrel 1 held fast in a bearing 8 by a set screw 9. This bearing is mounted on the top of a sewing machine, and the end of the mandrel of course goes into the cavity 3, and fits in snugly enough to hold the tip without letting it drop off. Both the cavity and the end of the mandrel are preferably slightly tapered. The correct point of I the cover H1 is then laid on the tip and the needle ll of the machine pushes the thread l2 through. the cloth and the hole 6 in the tip several times,

and wraps the thread around the tip. A strong and durable connection between the tip and the cloth cover results. The cavity 3 being tapered fits upon the end of each rib very tightly and virtually never comes off.

The sector shaped pieces or sections of the cover are indicated at l3 and the seams where the pieces are sewn together are indicated at It.

2 The knob 2 may becombinedwith: a collar-J5. merely for greater: neatness-and. ornamental effect, at the thinnest part of the tapered portion of the tip, which extends to the bore 6 near the inner end of the cavity 5.

The cavity 3, while it tapers and contracts to wards its inner end, is substantially square in cross section. The end of the rod 1 is also tapered and has the same cross section as the cavity 3. The cavity 3 terminates within the tip in a terminal surface l6 which is inclined or diagonal with respect to the length of the tip, and is inclined upward to the axis of the bore 6, as shown in Figure 4. The end I! of the rod is bevelled and inclined from the lower side to the upper in a direction away from the support 8. Hence, when the tip is seized in the operators fingers and held in the position of Figure 4, it can be pushed upon the rod 1 till the inside terminal surface It of the cavity and the bevelled surface 11 of the rod abut and make contact with each other fully over the entire extent of the terminal surfaces of both. A notch IS in the end of the tip shows which side of the tip should be uppermost to make the tip fit upon the rod so that the bore 6 alines with the needle l2. Sewing can now be performed because the needle will move freely through the bore 6 to put the threads in place.

If, however, the tip is wrongly held by the operator and pushed upon the rod as illustrated in Figure 6 with the notch l8 underneath, the operator will see at once that something is wrong. The inside terminal surface l6 of the cavity 3 will now slant downward towards the axis of the bore 6 and the beveled end I1 of the rod will not make contact with this surface over its whole extent. Instead it will strike the upper edge of the surface l6, where it intersects with one inner lateral surface of the cavity 3. The tip will thus be stopped before the bore 6 comes into alinement with the needle I 2, or directly under it; The operator now pulls the tip off and turns it as required.

The tip must of course be held with the bore 6 vertical to get it into position to be sewed by the needle; hence, there are only two positions possible. In each, the bore 6 will be vertical, but

in the wrong position of the two, with the notch l8 not on top, the bore will not be exactly under the needle I2. The operator of course will then know that more adjustment is necessary. The tip then only needs to be pulled off, given a half turn to bring up the notch l8 on top, and then put back on the rod I.

My invention thus embodies a very useful and practical form of tip which greatly reduces loss of time, waste of thread and other damage, and greatly increases the rate of production and finishing umbrellas in which it is used. The rod 1 can of course be supported with the bevelled end inclined downward and away from the support 8, to cooperate with the tip in the same way.

Having described my invention, what I believe to be new is:

1. A tip for an umbrella rib having a body with a cavity in one extremity, the inner end of said cavity being inclined, the tip having a thread receiving transverse bore through it between the extremities thereof, and an indicating notch at the entrance of the cavity.

15 2. The combination of a metal tip to be secured to the cloth cover of an umbrella and fitted upon the outer end of a rib thereof, a rod to hold said tip, means for holding the rod in fixed position, and a support to which the rod is afiixed, the tip having a cavity in one extremity to receive snugly the end of said rod to-mount it in position for fastening the cover thereto, the tip having a square in cross section.
